The statement x += 3 in Python is known as an augmented assignment operator. It is equivalent to saying x = x + 3. This means that the current value of x is increased by 3.

Here’s a breakdown of the options provided:

1. Increments x by 3: This is correct. The statement adds 3 to the current value of x and updates x with this new value.

2. Assigns 3 to x: This is incorrect. The statement does not assign 3 to x; instead, it modifies the existing value of x by adding 3.

3. Multiplies x by 3: This is incorrect. The statement does not perform multiplication; it only performs addition.

4. Divides x by 3: This is incorrect. The statement does not do any division; it adds 3 to the existing value of x.

In conclusion, the correct interpretation of x += 3 is that it increments x by 3.
